Rapid weight loss normally results in sagging skin due to stretching. As you lose weight quickly, your skin cannot conform to your new shape because the elasticity has been damaged. Your facial skin will show this with sagging jowls, neck and cheeks. Slow weight loss not only helps you avoid this problem but also increases your chances of keeping the weight off.
Exfoliate your face weekly to remove dead skin cells. This increases blood circulation, aiding in the formation of collagen fibers responsible for your skin's elasticity. Apply a moisturizing cream or skin tightening cream afterward to help protect your skin and maintain its natural moisture balance.
Build lean muscle in your face and neck by eating plenty of lean proteins found in poultry and seafood. Protein is required by your muscles to keep fibers healthy and increase muscle mass, thus decreasing fat and filling in sagging areas.
Perform facial exercises daily to help tighten your skin. Pucker your lips and hold for 5 seconds, or jut your chin out while looking up for 10 repetitions. Facial expressions and movement help build muscle and return your skin to its supple state.
Apply gels or lotions containing soy extract, aloe vera extract or yeast extract to your face after each cleansing. These products help tighten skin on your face by increasing collagen production and elasticity while reinforcing your skin's protection.
